Harness The Sun's Power With Solar PV Panels
Photovoltaic panels (PV) are the modern standard for sustainable living. By converting sunlight directly into electricity, you can power your home, charge your EV, and heat your water for free. PV panels explained simply: they use semiconductor cells to convert sunlight into usable electricity - no moving parts, no noise. Plus, through the Micro-generation Support Scheme, you can get paid for every unit of unused electricity you export back to the grid.
Whether you're looking at the cost of PV panels for a new build or a retrofit, LVP Renewables can help you find the right solution. With SEAI grant for PV panels available, now is the best time to invest in solar PV panels in Ireland.

PV Panel Dimensions & Sizes
Choose the right PV panel size for your roof and energy requirements.
Understanding PV Panel Size & Dimensions
Standard PV panel dimensions for residential use are approximately 1.7m × 1.0m (1.7 m²), while larger commercial panels can measure up to 2.1m × 1.3m. The size of PV panels you need depends on your available roof space and energy consumption.
Modern PV panels sizes come in various configurations. A typical 400 watt PV panel measures around 1.72m × 1.13m, while high-power 500W PV panels are slightly larger at approximately 2.09m × 1.13m. The PV panel wattage you choose directly impacts how many panels you'll need.
How many PV panels do I need? A typical 3-bedroom home in Ireland requires 8-12 panels for a 3-5 kW system. Use our guidance below to calculate how many PV panels you need based on your annual electricity consumption.
Popular PV Panel Sizes
- 370W Panel: 1.76m × 1.04m - compact, efficient for limited roof space
- 400W Panel: 1.72m × 1.13m - most popular residential choice
- 500W Panel: 2.09m × 1.13m - high-output for maximum generation
- 12V PV Panel: Compact panels ideal for off-grid setups, caravans & boats
PV Panel Output & Solar Calculator
Understand your potential solar PV panel output and calculate your savings.
Calculating PV Panel Output
PV panel output is measured in kilowatt-hours (kWh) and depends on panel wattage, orientation, tilt angle, and local weather conditions. In Ireland, a south-facing 1 kWp system typically produces 850-1,000 kWh per year. The best angle for PV panels in Ireland is between 30° and 35° facing south for maximum energy harvest.
PV panel output per m² averages around 150-200 watts under standard test conditions. The solar PV panel output of modern high-efficiency panels from brands like Longi PV panels and Mitsubishi PV panels can exceed 210W per m². Calculating PV panel output accurately requires considering shading, roof orientation, and local irradiance levels.
Our PV panel calculator tool helps you estimate your system size, expected output, and savings. A solar PV panel calculator takes into account your roof area, electricity consumption, and local conditions to give you an accurate projection. Contact us for a free PV panel simulation tailored to your property.
Output Guide by System Size
- 3 kW System (8 panels): ~2,600 kWh/year - covers ~50% of average home usage
- 5 kW System (12 panels): ~4,300 kWh/year - covers ~80% of average home usage
- 10 kW System (24 panels): ~8,500 kWh/year - ideal for larger homes or small businesses
- Annual Savings: Up to €1,500+ depending on system size and usage patterns
PV Panels vs Solar Panels & Panel Types
Understand the differences and discover which type of PV panel is right for you.
PV Panels vs Solar Panels - What's the Difference?
People often ask about PV panels vs solar panels. In reality, PV (photovoltaic) panels are a type of solar panel specifically designed to generate electricity. Solar thermal panels, on the other hand, heat water directly. When people refer to "solar PV panels", they mean panels that convert sunlight into electricity.
At LVP Renewables, we supply the best solar PV panels in Ireland from leading manufacturers including Longi PV panels and Mitsubishi PV panels. These premium brands offer excellent durability, high efficiency, and strong performance even in Ireland's variable climate.
Balcony & Wall-Mounted PV Panels
Balcony PV panels are an increasingly popular option for apartment dwellers and those with limited roof space. These compact plug-in systems can be mounted on balcony railings or walls to generate electricity directly.
Wall-mounted PV panels provide a versatile alternative when roof installation isn't feasible. They can be fitted to south-facing walls for optimum energy generation. While the output is typically lower than roof-mounted systems due to the angle, they still provide valuable electricity generation and cost savings.
PV Panels with Battery Storage
Combining PV panels with battery storage maximises your energy independence. A battery for PV panels stores excess electricity generated during the day so you can use it in the evening when the sun goes down. This means higher self-consumption and lower bills.
PV panels and battery storage systems are now more affordable than ever. A typical 5 kWh battery costs between €3,000 and €5,000, and when paired with a PV system, it can significantly increase your savings. You can also use your stored energy as backup power during outages.
Interested in using PV panels to heat water? By connecting your PV system to an immersion diverter, excess solar electricity can automatically heat your hot water cylinder - giving you free hot water during sunny periods. This is one of the most cost-effective ways to utilise your solar PV panel output.
Learn About Battery StorageBenefits of Battery Storage
- Store excess solar energy for evening and nighttime use
- Increase self-consumption from 30% to over 70%
- Backup power during electricity outages
- Use PV panels to heat water via an immersion diverter
- Faster PV panel payback period with maximised savings

Common Questions About PV Panels
What are solar PV panels and how do they work?
Solar PV (photovoltaic) panels convert sunlight directly into electricity using silicon cells, rather than heating water like solar thermal panels do. The electricity generated can power your appliances, charge an EV, or be stored in a battery, with any unused power exported back to the grid.
Are there grants available when I buy solar PV panels in Ireland?
Yes. The SEAI grant for domestic rooftop solar will remain at €1,800 for 2026, and a 0% VAT rate applies to the supply and installation of solar panels on private residences, which adds further savings on top of the grant. To qualify, your installer must be SEAI-registered and the property must have been built and occupied before 2021.
Do solar PV panels work in Ireland's cloudy climate?
Yes. Solar panels generate electricity from daylight rather than direct sunshine, and still produce 20 to 40% of full output on a cloudy day, so they remain effective and cost-efficient across Ireland's weather, not just in summer.
Can I sell excess electricity from my solar PV panels?
Yes. Any electricity your panels generate but don't use is automatically exported to the grid, and you're paid for it through the Micro-generation Support Scheme (also known as the Clean Export Guarantee). This adds to your annual savings on top of reduced electricity bills.
Is it worth buying solar PV panels in Ireland right now?
With the SEAI grant confirmed at Up to €1,800 for 2026, 0% VAT on installation, and rising electricity prices, most systems pay for themselves within 5 to 8 years and continue generating savings for 20+ years after that. Combined with rising property values from an improved BER rating, it remains a strong long-term investment.
How many solar PV panels do I need for my home?
This depends on your roof space, electricity usage, and budget, but most 3-bed semi-detached homes in Ireland install around 10 panels (roughly 4.4 kWp), which also maximises the SEAI grant. Larger or higher-usage households may need 12 to 16 panels for the best long-term savings.
